To all whom it may concern: 7

Be it known that I, VICTOR E. EDWARDS,

a citizen of the United States, residing at \Vorcester, in the county of Worcester and Commonwealth of Massachusetts, have in-- vented a new and useful Improvement in a Feeding Mechanism for Rolling Mills, of which the following is a specification, accom' panied by drawings forming a part of the same, and in whichv Figure 1 represents a plan view of my improved feeding mechanism, showing a series of rolls in a rolling-mill and aheating furnace shown in horizontal sectional view with the furnace located in juxtaposition to the first pair of rolls of the rolling-mill. Fig. 2 is a top view of my improved feeding mechanism, shown on a larger scale. Fig. 3 is a side view of the same; and Fig. 4 is a vertical sectional view on line 4 4-, Fig. 2.

Similar letters and numerals refer to similar parts in the different figures.

The object of my invention is to provide a feeding mechanism by which heated billets delivered from a single delivery-openingof the heating-furnace may be fed to a pair of rolls having two sets of circumferential grooves or passes and directed at will to either of the passes of the rolls; and my invention consists in the construction and 'arrangement of parts, as hereinafter described, and set forth in the annexed claims.

Referring to the accompanying drawings, 1 denotes a furnace for heating billets, containing a heating-chamber 2, provided with suitable openings for the admission and delivery of ingots and a pushing mechanism by which ingots are pushed by an endwise movement through the delivery-opening of the furnace. 'The furnace shown in the drawings is provided with an opening 3 for the admission of billets into the heating-chamber by an end- Wise movement, a pushing mechanism 4, by which the billets are pushed by a sidewise movement across the heating-chamber and into alinement with thedelivery-opening 5. Opposite the delivery-opening 5 is an opening 6 to receive a pushing mechanism for the purpose of pushing the heated billets by an endwise movement through the delivery-opening 5, said pushing mechanism consisting in the present instance of the forked pushingbar 7, by which the bar 7 is given an endwise movement. The pushing-bar 7 may be operated by hand or it may be given an endwise movement by means of a bar or rotating rolls. (Not shown.) Opposite the delivery opening 5 is located the first pair 8 of the series of rolls forminga continuous rolling-mill and provided with two sets of circumferen- 6o tial grooves or passes 9 and 10. Between the fi'rst'pair of rolls 8 and the delivery-opening 5 of the furnace I place a table 11 in the same horizontal plane as the delivery-opening and ing above the upper surface of the table 11, is a wing 12, located at the end of the tablenext the furnace and placed obliquely to the line of motion of the heated billets and in proper position to crowd the advancing end of the billet as it emerges through the delivery-opening 5 into line with the pass 9 of the rolls, so that when the billet has been pushed in front of the delivery-opening 5 by the pushing mechanism 4:- the forked bar 7 is applied to the rear end of the billet and pushed forward 'by an endwise movement through the delivery-opening 5, and in case the billet is out of alinement with the pass 9 of the rolls it will strike the wing 12 and be laterally deflected into alinement with the pass 9. One corner of the table 11 is cut away to provide space for the plate 15, with its upper surface normally in the same plane as theupper surface of the table 11 and provided on one side with an upwardly projecting rib 16, having its side 17 arranged obliquely to the line of motion of the billet and adapted to act as a guide for directing the advancing end of the billet into the pass 9 of 0 the rolls. The plate 15 is mounted upon the free end of an arm 18, pivoted at its opposite end to a lug 19, depending from the under side of the table 11. The free end of the arm 18 is pivotally connected to a piston-rod 20, 5 which is actuated by a hydraulic'cylinder 21, provided with the usual valves and valve-controlling mechanism, by which a reciprocating motion is given at will to the piston-rod 20 in order to raise the plate 15 from its normal po Project- 65 sition to that indicated in Fig. 4. In front of the passes 9 and 10 I place the guide-blocks a b c, forming flaring or funnel-shaped openings to the passes.

The operation of my feeding mechanism is as follows: The plate 15 is lowered into the plane of the table 11 and a heated billet in position before the delivery-opening 5 is engaged by the forked pushing-bar 7 and pushed forward until its end enters the pass 9 of the rolls with the billet in position indicated at A, Fig. 2. lVhen the advancing end of the billet A has entered between the rolls, the plate 15 is raised into the position shown in Fig. 4, thereby lifting that portion of the heated billet A which lies across the plate 15. A second billet is then pushed forward by an endwise movement along the side of the billet A in the position indicated at B, Fig. 2, until its advancing end strikes against the oblique side 23 of the plate 15, which, having been raised above the plane of the table 11, serves as a guide to turn the forward end of the billet through the space between the surface of the table and the raised billet A and direct it into alinement with the pass 10 of the rolls, allowing both billets A and B to pass through the grooves 9 and 10 of the rolls simultaneously, the billet A passing through the groove 9 and the billet B crossing beneath the billet A in front of the oblique side 23 of the lifting-plate l5 and passing through the groove 10 of the rolls. In case the billetAhas passed through the rolls the raising of the plate 15 will deflect the billet B into alinement with the groove 10, and by the lowering of the plate 15 the next billet will pass over the plate 15 and into the groove 9. The raising and lowering of the plate 15 therefore controls the destination of the billets into the grooves 9 and 10, and the raising of the plate 15 also serves to lift any billet which at the time may lie across it, so as to provide space for passage of the succeeding billet along the oblique side 23 of the plate 15.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination with a pair of rolls, having two sets of grooves, or passes, in the same horizontal plane, of means for moving a billet by an endwise movement into engagement with said rolls, a fixed guide by which the advancing end of the billet is deflected horizontally to one side and brought into alinement with one of "said passes, a movable guide by which the second billet is deflected horizontally in the opposite direction and brought into alinement with the other of said passes, substantially as described.

2. The combination with a pair of rolls having two sets of grooves, or passes, of means for movinga billet endwise into engagement with said rolls, means for guiding the advancing end of the billet into one of said passes, a vertically-movin g guide adapted to be brought into the path of the second billet and deflect the same into the other of said passes and means for raising said movable guide, substantially as described.

3. The combination with a pair of rolls having two sets of grooves, or passes, of means for moving a billet endwise into engagement with said rolls, a table in front of said rolls, by which the billets are supported,in the plane of said passes, a fixed rib projecting from the upper surface of said table and adapted to push the billet sidewise and into alinement with one of said passes, a movable guide normally below the surface of said table, means for raising said movable guide above the surface of the table, whereby the second billet as it is pushed into contact with said movable guide is moved into alinement with the other of said passes, substantially as described.

4. The combination with a pair of rolls having two sets of grooves, or passes, of means for moving a billet endwise into engagement with said rolls, a table in front of said rolls and adapted to support the billet in the plane of said passes, means for guiding the billet into one of said passes, a plate lying normally in the plane of the table and in the path of the billet, means for raising said plate and thereby lifting the billet passing over it and means for guiding the succeeding billet into the other of said'passes and beneath the billet passing over said plate, substantially as described.

5. The combination with a pair of rolls having two sets of grooves, or passes, of means for moving abillet endwise into engagement with said rolls, of means, for guiding the billet into one of said passes, means for lifting the billet during its passage between the pair of rolls, and means for guiding a succeeding billet beneath the raised billet and into the other of said passes, substantially as described.

6. The combination with a pair of rolls having two sets of grooves, or passes, of a pushing-bar adapted to engage the end of a billet, means for moving said barendwise, whereby the billet is pushed by an endwise movement into engagement with said rolls, a table in front of said rolls and in the plane of said passes, guides for conducting the advancing end of the billet into one of said passes, a plate lying in the plane of said table and in the path of the advancing billet, an arm hinged atone end, and supporting said plate upon its free end, means for rocking said arm and raising said plate, whereby a billet passing over said plate is raised from said table, said plate having an oblique side arranged to be brought into the path of a succeeding billet by the raising of the plate, whereby the succeeding billet is conduced beneath the raised billet into the other of said passes, substantially as described.
